This adds the missing bits to support the USB-C Altmode support on SM8550. These are the following changes since the previous SM8450 SoC: - No more GLINK altmode events for USB only changes, only DP - Type-C orientation is available on a PMIC signal connected to a GPIO line - When altmode is disconnected, an 0xff mode event is sent. The 0xff altmode is translated as a SAFE type-c mux mode. The fact No more GLINK altmode events for USB needs to be resolved in a separate patchset. Redriver driver & bindings dependency at [1].
